Filter by Keyword13 report(s) found with delays in the keywords field Due to the short construction season in Wyoming, contractors must complete many transportation projects on a tight schedule. Unfortunately, contractors often cannot create accurate schedules considering logical work ordering, reasonable productivity, and weather events. Inaccurate baseline schedules... The State of Wyoming road network is characterized by heavy truck traffic. In 2015, truck traffic was approximately 22% of vehicle miles traveled (VMTs) along all routes in Wyoming, according to the WYDOT Annual Traffic Report. The heaviest truck traffic exists along I-80 with about 47% truck VMTs. Trucks... This report describes methods that potentially can be incorporated into the performance monitoring and planning processes for freeway performance evaluation and decision making. Reliability analysis was conducted on the selected I-15 corridor by employing congestion frequency as the performance measure.... The goal of this study is to evaluate light rail priority strategies along the 400 S / 500 S corridor in Salt Lake County through analyzing benefits and impacts of the priority on transit and vehicular traffic through microsimulation. The results show that the existing priority strategies have no impacts... This study evaluates the impact of proposed replacement on the travelers in Summit County. The purpose of this research is to provide UDOT an estimation of possible delay costs due to congested traffic resulting from the proposed work zone scenarios. The VISSIM micro-simulation tool is used to build... With ever-increasing traffic demand and price of fossil fuels public transit becomes more popular transportation mode than ever before, especially in the fast growing regions such as Salt Lake City Metropolitan Region. Wasatch Front Regional Council (WFRC) (a local Metropolitan Planning Organization)... Earthquakes damage transportation infrastructure. In addition to replacement and repair costs for damage to transportation structures, large earthquakes can increase time delays resulting from a network component's loss of function. Damage to the network can severely disrupt traffic flows for several... In 2005, the Utah Department of Transportation (UDOT) installed the Sydney Coordinated Adaptive Traffic System (SCATS) in Park City, Utah, on its network of 14 signalized intersections. A field evaluation compared previous time-of-day actuated-coordinated signal timings with those dynamically computed... This paper evaluates the impact of various I-15 reconstruction closure scenarios on the travelers in the Ogden area. The purpose of the research was to investigate the impact of the scenarios and facilitate decisions about future maintenance of traffic during the reconstruction. This paper presents preliminary results of the VISUM Online validation. It compares traffic conditions estimated by VISUM Online to measured data. The results show that VISUM Online produces comparable traffic measures. |
